CLEANER AND GAUGE FOR \VINDING MACHINES.

. Application filed March 8, 1922. Serial No. 541,947.

To all whom it may concern:

Be it known that I, MAURICE l v nrn'- smile, a citizen of the United States, resid at East Cleveland, in the county of (luyahoga and State of Ohio, have invented a certain new and useful Improvement in Cleaners and Gauges for Winding halachines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention is a novel construction of cleaner and gauge for use in connection with machines for winding wool, silk or other material, the object, of the invention being to provide a cheap and simple device which can housed in connection with any of the standard types of winding machines and one which will be more durable than the devices now in use and also capable of exceedingly fine adjustments.

Another object of the invention is to so construct and arrange the parts as to facilitate the introduction of a thread or yarn to the device, and a still further object is to so construct the adjusting parts of the device that when once adjusted they will remain fixedin such adjusted positions.

It is well known that Wool, silk, cotton and similar thread material as manufacturedcontains certain imperfections either in the way of foreign matter adhering to the thread, or excessive material at certain points, and inasmuch as the uniform dimension of thread or strand is desirable in knitting and weaving, it is customary in winding the thread or strand to clean or scrape the same so as to remove all surplus or foreign matter so that the thread or strand as finally wound will'be of uniform dimension.

While cleaners or scrapers have been employed in connection with various types of winding machines. they have proven only partially successful owing to the difliculty of maintaining accurate adjustments, and for various other reasons. As before stated, the object of my invention is to provide a simple and easily adjusted device which will ren'iedy all of these various defects.

With these objectsin view my invention consists in the novel features of construction and also inthe manner of combining or arranging the same, all of which will be hereinafter fully described. and set forth in the appended claims.

In the drawings forming part of this specification, Fig. 1 is a face view of one form of cleaner or scraper embodying my invention together with a guide arranged in advance thereof, both the cleaner and guide being connected to a bar attached to the frame of a winding machine; Fig. 2 is a plan view showing the cleaner and guide,

bar and arms connecting the cleaner and guide to the bar; Fig. 3 is a side view of the cleaner arranged upon the upper end of a vertical'arm; Fig. 4 is a face view of the same; Fig. 5 is a view from theopposite side; Fig. 6 is an enlarged sectional view, partly in elevation, of the fixed and movable blade carrying members and means for adjusting the same; F ig. 7 is a detail sectional view on the line 7-7 of Fig. 6; Fig. 8 is a detail sectional view on the line 88 of Fig. 6, the screw being shown in elevation; and Fig. 9 is a detail view showing a portion of the movable blade carrying member.

In the practical embodiment of my invention, I employ a supporting arm A which is connected to any suitable portion of the machine frame or to a bar A attached to said frame, as shown in Figs. 1 and 2 in which case the arm A is arranged horizon-- tally, whereas in Figs. 3, l and 5, the arm A; is shown connected directly to the ma chine frame and in vertical position. The cleaner or scraper proper comprises two block-like members B and C to which are connected the cleaner or scraper blades D and E, respectively. The member B, which I term the fixed member, is rigidly connected to the arm or rod A, the lower end of the fixed member being bored'both vertically orhorizontally to receive the end of the arm, and a set screw F is employed to securely connect the said member B to the arm or rod A. I V

The movable member C is adjustably connected to the fixed member B by means of aditferential screw G and a threaded bushing H, the bushing H being both internally and externally threaded, the interior threads being somewhat coarser than. the exterior threads. The bushing H is screwed into the fixed member B and is rigidly secured by means of a'lock nut H. The screw Gr consists of the reduced portion G having a thread corresponding to the interior thread of the bushing H While the larger portion G has a thread corresponding with the exterior thread of the bushing FT and screws into the threaded bore of theniov-v able member, and the head portion G of the screw is adapted to fit into the circular recess 1 coummnicating with the threaded bore I. The head of the screw is provided with a polygonal recess or socket (i into which the corres 'iondingly shaped end of a wrench can be placed for the purpose of turning the screw in either direct-ion and the periphery of the screw head is provided with graduations G which cooperate with an indicating mark placed upon the blade E and by means of which the amount of adjustment can. be readily gauged. It, is obvious that by turning the screw. in one direction the movable member (I will be brought toward the fixed member and when turned in the opposite direction will be positively moved in the opposite direction. and. by having the differential screw and the bushing for effecting this lateral. movement, 1t isobvious that I am able to effect a very fine adjustment, and by lnWing't-he bushing adjustable as well as the screw, any inaccuracies which might occur due to the wear of parts can be corrected. In order to guide the block C in its movements and insure parallelism at all times, I employ a guide piece K which is rigidly connected to the block C by a screw K. and projects laterally therefrom. This guide piece K is preferably square in cross section and fits into a correspondingly shaped recess cut in the face of the block C and the other end of the guide piece works in a correspondingly shaped guideway K cut in the'face of the fixed member B as most clearly shown in Figs. 3,. 5, 6 and 7. The blades D and E are preferably made of good quality of steel and are not only machined-along their edges D and E, but also have their outer faces machined so that their front edges are in reality shearing edges so that small threads projecting from the main thread or strand will be sheared or trimmed off as it passes between the blades. The blades D and E are attached to the front faces of the fixed and movable members by means of screws D and E respectively, said screws passing through the blades and entering threaded holes produced in the fixed and movable members and in addition to the screwsD and E I provide a set screw D which: works.

through a slot D produced near the end of the blade D, the shank of the screw D working into av threaded hole D produced in the guide piece K, it being understood that when it is desired. to adjust the blades through the, medium of the differential and C at the outer sides of said members and the outer side edges of the blades are fitted firmly against these stop flanges and by having the outer edges accurately machined and the contacting faces of the flanges correspondingly machined, I obtain great accuracy in the positioning of the blades upon the fixed and movable members. The flanges B and C are interrupted or removed for the placement of the guide piece, and the flange C and a portion of the fixed member C is also removed in order to expose, the graduated head of the adj usting screw. Near the lower end of the fixed member 0, I produce a recess L and in the fixed member B I produce a transverse bore M which is adapted to align with the recess L and in this recess and bore I arrange the glass or porcelain roller L over which the thread passes, and this roller is held against lateral displacement by means of a screw plug 0 which is screwed into the outer end of the transverse bore M, but the roller has a limited amount of lateral movement and at the same time turns freely in the bore and recess so that the roller will turn freely and move from side to side so that wear upon the surface thereof will be reduced into contact with the roller. The fixed member 13 is preferably made somewhat longer than the movable.member C and the blade Dis also made somewhat longer and is rounded at its extreme lower end. The blade E is formed with the downwardly and outwardly inclined portion E below the end of the movable member and then is provided with the upwardly and outwardly extending portion E the end of which is rounded and the lower outer edge of the movable member C is also cut away and rounded as most clearly shown at C in Figs. 2, 5 and 9. Shaping the blades in the mannerherein described facilitates the introduction of, the thread or strand into the spacebetween the cleaning blades irrespective of whether the blades are projecting downwardly, upwardly or. laterally.

It will thus. be seen that I provide an exceedingly cheap and simple device which can be quickly and easily connected to. any of the present standard types of Winding machines and can be arranged in various positionsaccording to the direction of travel or position of the thread which isbeing cleaned and gauged. By means of the differential screw and bushing, I am; able to obtain positive movement in either direction of the movable member, and furthermore I am able to obtain exceedingly fine adjustments during such movements, and in case any inaccuracies should become apparent due to the wear of parts, this can be readily compensated by the adjustment of the bushing in the fixed member.

The manner of arranging the glass or porcelain roller between the fixed and movuble member renders the movement of said glass or porcelain roller free and easy both rotatively and laterally, and the roller can also be quickly removed and replaced when desired. By having the guide flanges upon the outer sides of the fixed and movable members fend placing the blades directly against said flanges, said blades are quickly and easily positioned in proper perpendicular positions, and by having both the front faces and the contiguous edges of the blades machined true, sharp edges or corners are provided, which trim elf any small threads or other projections which might ordinarily pass between the gauged blades without being sheared. The peculiar shape of the lower or outer end of the blade attached to the movable. member has been found to be extremely helpful in quickly and easily guiding the thread or yarn into the converging space between the blades. The guide piece K which is attached to one of the members and movable in the other member insures the proper parallelism of the movable member with reference to the fixed member and consequently maintains the blades in proper parallel relation at all times.
